“…The challenge with the VistaCam device in its current optical configuration is that it is not designed for use in the periodontal pocket environment, but if suitable changes were made in this direction, the results from this study show promise for its eventual use for guiding clinicians in the detection of subgingival calculus. The overall approach then would be similar to using laser fluorescence to inform the decision around stopping or continuing subgingival calculus debridement (Folwaczny, Heym, Mehl, & Hickel, 2002; Krause, Braun, & Frentzen, 2003; Folwaczny, Heym, Mehl, & Hickel, 2004; Shakibaie & Walsh, 2012). …”

The VistaCam® intra‐oral camera system (Dürr Dental, Bietigheim‐Bissingen, Germany) is a fluorescence system using light emitting diodes that produce a 405‐nm violet light. This wavelength has potential application for detection of dental calculus based on red emissions from porphyrin molecules. This study assessed the digital scores obtained for both supragingival and subgingival calculus on 60 extracted teeth and compared these with lesions of dental caries. It has also examined the effect of saliva and blood on the fluorescence readings for dental calculus. VistaCam fluorescence scores for both supragingival (1.7–3.3) and subgingival calculus (1.3–2.4) were higher than those for sound root surfaces (0.9–1.1) and dental caries (0.9–2.2) (p < .05). The readings for calculus samples were not affected by the presence of saliva or blood. These results suggest that the use of violet light fluorescence could be a possible adjunct to clinical examination for deposits of dental calculus.

“…To assist dental practitioners in detecting deposits of subgingival calculus, a number of novel methods have been developed, including visible red light (655 nm)-induced fluorescence (LF) [5,6]. This approach has been used in three systems from the one manufacturer (Kavo, Biberach, Germany) -the "classic" DIAGNOdent, the DIAGNOdent pen, and the KEY3 laser.…”

Abstract:Visible red (655 nm) laser fluorescence (LF) devices have potential use for identifying deposits of subgingival calculus on the root surfaces of teeth during dental examination and treatment, however the performance of commercially available LF systems has not been examined in detail. This laboratory study explored the correlation between LF digital readings and the surface area and volume of subgingival calculus deposits on teeth. A collection of 30 extracted human posterior teeth with various levels of subgingival deposits of calculus across 240 sites were used in a clinical simulation, with silicone impression material used to replicate periodontal soft tissues. The teeth were scored by two examiners using three LF systems (DIAGNOdent, DIAGNOdent Pen and KEY3). The silicone was removed and the teeth removed for photography at 20X magnification under white or ultraviolet light. The surface area, thickness and volume were calculated, and both linear least squares regression and non-linear (Spearman's rank method) correlation coefficients determined. Visible red LF digital readings showed better correlation to calculus volume than to surface area. Overall, the best performance was found for the KEY3 system (Spearman coefficient 0.59), compared to the classic DIAGNOdent (0.56) and the DIAGNOdent pen (0.49). These results indicate that visible red LF systems vary somewhat in performance, but all can provide a useful estimation of the volume of subgingival calculus present on teeth.

“…Most recently, 655 nm InGaAsP (indium gallium arsenide phosphate) diode laser radiation has been included in an Er:YAG laser device to induce fluorescence in subgingival calculus (Folwaczny et al 2002, Krause et al 2003. Preliminary clinical and histological results have shown that fluorescence-controlled (feedback system) Er:YAG laser radiation enabled an effective removal of subgingival calculus and a predictable root surface preservation in comparison with hand instruments (Schwarz et al 2006, Krause et al 2007).…”
